IPC: H01L21/265
Filed: 1989-12-27
Abstract: PURPOSE:To prevent generation of alignment error and optimize fine working by eliminating a silicon nitride layer by oblique etching, and using the side wall of a gate electrode of a left silicon nitride layer part as a self alignment mask. CONSTITUTION:An oxide film 2 and poly silicon are arranged on a silicon substrate 1, and a gate electrode 3 is constituted. After a nitride film 4 is formed so as to cover the whole part of the electrode 3, the film 4 is subjected to oblique etching. The nitride film except the part turning to a shadow of the electrode 3 in the etching direction is eliminated, and the left nitride film part is made a side wall 5. After an N<-> region 6 is formed by ion-implanting phosphorus in the surface of the substrate 1, the whole part is subjected to wet oxidizing process. Thus the region except the film 4 is oxidized, a film 2 is grown, a thick oxide film 7 is formed, and crystal defect of the region 6 is compensated. After the other side wall part 8 is formed, arsenic (As) is ion-implanted, and an N<+> region 9 is formed by annealing. Thereby fine working can be optimized without generating alignment error.

Filed: 1994-12-13
Abstract: PURPOSE: To prevent the unstable drive of a transistor for switching and to stabilize the circuit operation by stopping the oscillation after lowering the high-frequency wave output once as an abnormality preventive operation. CONSTITUTION: The point (b) of an abnormality detecting circuit 15 has a timer function to operate after a necessary preheating time elapses from the time when the voltage at the point (a) is detected. When the service life of a discharge lamp 20 in the lighting condition comes to the final period, the voltage at the point (a) is raised, and its abnormal condition is detected. As a result, the point (b) is made to the level L, a converting transistor Tr13 is turned off, so as to transfer from a lighting frequency to a preheating frequency and the output fed to the discharge lamp 20 is lowered. After a specific time elapses, the point (c) of the circuit 15 is made to the level H, an oscillation stopping transistor Tr19 is turned on and the oscillation of a lighting circuit is stopped. Since the oscillation is stopped after the output is lowered once, an excessive stress is never applied to the parts used in the circuit and a protective operation can be carried out at a low cost.

Title: Combustion control device for internal combustion engine
Inventor: MIZUNO HIROYUKI
IPC: F02D43/00
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To stabilize combustion and to prevent a failure in ignition by making a compensation added to one of an ignition timing and a fuel injection timing when the indicating opening of a swirl control valve is different from the actual opening of the valve even if an actual engine load is different from the theoretical engine load. SOLUTION: For example, when an engine 1 is accelerated or decelerated, a basic amount of injection of fuel is different from the amount of gradually changed injection of fuel because of gradual change compensation and the amount of gradually changed injection of fuel is injected into the engine 1. An electronic control unit(ECU) 30 calculates a target opening of a swirl control valve 17 based on the amount of gradually changed injection of fuel and compensates an ignition timing and fuel injection timing based on a deviation between the target opening and the actual opening. Therefore, for example, even when the engine 1 is accelerated or decelerated, the ignition timing and the fuel injection timing are compensated in a suitable state.
